is a valuable landscaping tree that is appreciated worldwide. However, the optimal environmental conditions for . cultivation have yet to be studied in detail, which hinders the preservation of wild resources of this plant and its commercial exploitation. The maximum entropy model was applied to assess the significance of environment variables influencing . distribution. Combining data from 629 global distribution points for . , predictions were made on the potential effects of climate change on the geographical distribution of suitable habitats for this species in the present and the future. The results indicated that . preferred a warm and humid growing environment. Under the current climatic conditions, the potential habitats for . were mostly located in the eastern coastal areas of the continents at medium and low latitudes. The main environmental variables that affected its distribution were the precipitation during the warmest quarter, the temperature seasonality, and the mean temperature of the warmest quarter. The analysis indicated that the continuation of current trends in climate change will result in the further reduction of suitable habitats for . growth, and the global centroid will shift to the southeast. These findings provided insight into the impact of climate change on . habitats, as well as provide guidance for the conservation of wild resources of this species and the breeding of more climate change-resistant varieties for the future.
是一种珍贵的园林树木，在全球范围内受到赞赏。然而，其栽培的最佳环境条件尚未得到详细研究，这阻碍了该植物野生资源的保护及其商业开发。应用最大熵模型评估影响其分布的环境变量的重要性。结合来自629个全球分布点的数据，对气候变化对该物种当前和未来适宜栖息地地理分布的潜在影响进行了预测。结果表明，其偏好温暖湿润的生长环境。在当前气候条件下，其潜在栖息地大多位于中低纬度大陆的东部沿海地区。影响其分布的主要环境变量是最暖季度的降水量、温度季节性和最暖季度的平均温度。分析表明，气候变化当前趋势的持续将导致其生长适宜栖息地的进一步减少，全球重心将向东南转移。这些发现深入了解了气候变化对其栖息地的影响，也为该物种野生资源的保护以及未来培育更多抗气候变化品种提供了指导。
